Why have just one go-to workout routine when you can have three? Actress Jamie Chung and husband Bryan Greenberg (from How To Make It In America and One Tree Hill) stopped by the New York Sports Club pop-up lab last week in NYC for a training session with Kira Stokes. While completing just one of the mini circuits the duo did could be considered a killer workout, Chung and Greenberg did all three. Yeah, they’re freaking fitness rock stars.

If you’re short on time, or just easing back into a regular training routine, give one of these mini circuits below a try. And when you’re ready, stack the circuits back-to-back for a sweat-dripping, muscle-shaking workout.

Workout 1: 3-Move Total-Body Circuit

Start with a TRX chest press.

Face away from wherever you have your TRX anchored with feet a little more than hip-width to shoulder-width apart. Grab the TRX handles with an overhand grip and extend your arms in front of you at shoulder height. Lean forward so your body is on a slight diagonal. Bend your elbows and lower your chest so it is lined up between your hands. Push back to start. Do as many reps as you can for 35 seconds.

Then do a knee tuck to pike up combo using a stability ball.

Start in a high plank position with your hands on the floor and stability ball under the tops of your feet, ankles, or lower shins. From here, bring your knees toward your chest in a tuck position as you roll the ball toward you. The ball should stay under your shins and ankles. Roll back to starting position. From there use your abs to raise your hips toward the ceiling in an inverted V position. Slowly lower back to your starting plank position. That’s 1 rep. Do as many reps as you can for 35 seconds.

Finish the circuit with a med ball slam.

Stand tall with your feet about shoulder-width apart. Your legs will be slightly bent. Hold a medicine ball overhead. Bring the ball forward and bend your knees to lower into a squat position while slamming the ball down (as hard as you can) on the floor in front of you. Pick up the ball and repeat. Do as many reps as you can in 35 seconds.

Now repeat this entire circuit 3 more times.

Workout 2: 4-Minute Kettlebell Tabata

This quick routine is great for when you’re working out with a friend or partner. To do it, you need to know how to do two moves:

1. Kettlebell squat press: Start standing tall and hold the kettlebell at the horns at chest height. Bend your knees and hinge at hips to lower into a squat (as Chung is demonstrating in the picture above). As you stand up, straighten your arms and raise the kettlebell overhead. Immediately lower into your next squat. If this is too challenging, skip the overhead press and just perform weighted squats.

2. Kettlebell push-up: Start with your right hand on the kettlebell and your left hand on the floor (see Greenberg in the picture above). Bend your elbows and lower your torso toward the ground to complete one push-up. Drop to your knees if you need.

The workout: Do four rounds of 20 seconds of work/10 seconds of rest of exercise 1. (For kettlebell push-ups, switch sides with each round.) Then, switch exercises and complete another four rounds of the same 20 seconds on/10 seconds off format.

Workout 3: Battle Rope AMRAP

AMRAP stands for as many rounds as possible, and for this workout you have four minutes to really push it. You'll need a battle rope in order to do this routine (you can find one stashed in a corner at most local gyms). Here's what one round entails:

20 double waves: Start with your feet shoulder-width apart with a slight bend in your legs. Grab one end of the rope in each hand with palms facing each other. Bend your knees slightly, engage your core, and move both arms up and down together to create double waves with the rope (as pictured above).

20 alternating waves: Now raise one arm to shoulder level and quickly lower to starting position, raising the other arm to shoulder level. Keep alternating as fast as you can go.

5 power slams: Bring both arms overhead and then slam the ropes down to the ground with as much force as you can, lowering into a deeper squat as you go. Straighten up to return to a standing position and repeat.

5 burpees: You know the drill...drop the ropes and bring your hands down to the floor. Jump your feet back so that you’re in a high plank position. Add a push-up here if you’re up for a challenge, then jump feet back towards hands and jump straight up. That’s 1 rep.
